[PATCH ghak105 V3sup] audit: hide auditsc_get_stamp and audit_serial prototypes

[Richard Guy Briggs]

auditsc_get_stamp() and audit_serial() are internal audit functions so
move their prototypes from include/linux/audit.h to kernel/audit.h
so they are not visible to the rest of the kernel.

Signed-off-by: Richard Guy Briggs <rgb at redhat.com>

Passes audit-testsuite with CONFIG_AUDITSYSCALL set automatically and
passes expected tests with it turned off manually.
